Yes, that is the only problem with the remnant bin! That's I tend to do better with drapery remnants, as they can be up to just under 3 yards, whereas for apparel fabric, it's 1 yard, and I've found that is sometimes enough for things like 18th c jackets, or even just trim.

And really, most of the time I'm in there, I find absolutely nothing, so it's just luck, I suppose!
